Lang leaps ahead in Korea, Park closes in (Reuters)

INCHEON, South Korea (Reuters) - U.S. Women's Open champion Brittany Lang posted a seven-under-par 65 to move into a one-shot lead over Alison Lee after the second round of the KEB Hana Bank Championship on Friday.

Cristie Kerr and Park Sung-hyun matched Lang's 65 to move into joint third, three strokes off the pace on seven under.

After a poor opening round of 75, world number one Lydia Ko got back to level after shooting three under. Thailand's Ariya Jutanugarn, hot on Ko's heels in the LPGA points race, struggled again at the SKY 72 Golf Club, posting a second straight 73.
